Abstract (en)
[origin: WO2006061204A1] The invention relates to a mixing circuit comprising a charge circuit (LC), an oscillating circuit inlet step (S1, S2) which is connected to a circuit which feeds an oscillating signal, and a signal inlet step (DTS1, DTS2). The oscillating circuit inlet step (S1, S2) comprises at least two bipolar-transistors (Q1, Q2) and the emitters thereof are connected to a constant potential (Vy) which is independent from the oscillating signal. The mixing circuit is used, preferably, in a base station or a mobile radio device of a cellular radio network.
